FlatLaf Change Log

1.0-rc4-SNAPSHOT

New features and improvements

• Extras: UI Inspector: Tooltip is no longer limited to window bounds.

Fixed bugs

• TabbedPane: Custom TabbedPane.selectedForeground color did not work when TabbedPane.foreground has also custom color. (issue #257)

1.0-rc3

New features and improvements

• Extras:
  • UI Inspector: Use HTML in tooltip. Display color value in same format as used in FlatLaf properties files. Added color preview.

Fixed bugs

• Label and ToolTip: Fixed font sizes for <code>, <kbd>, <big>, <small> and <samp> tags in HTML text.
• Fixed color of <address> tag in HTML text.
• IntelliJ Themes: Fixed table header background when dragging column in "Dark Flat" and "Light Flat" themes.
• CheckBox: Fixed background of check boxes in JIDE CheckBoxTree. (regression in 1.0-rc2)

1.0-rc2

New features and improvements

• Button:
  • In "Flat Light" theme, use a slightly thinner border for focused buttons (because they already have light blue background).
  • In "Flat Dark" theme, use slightly wider border for focused buttons.
• CheckBox and RadioButton: In "Flat Dark" theme, use blueish background for focused components.
• Tree: Support disabling wide selection per component. (set client property JTree.wideSelection to false). (PR #245)
• Tree: Support disabling selection painting per component. Then the tree cell renderer is responsible for selection painting. (set client property JTree.paintSelection to false).
• JIDE Common Layer: Support JidePopupMenu.

Fixed bugs

• Button: Fixed behavior of Enter key on focused button on Windows and Linux, which now clicks the focused button (instead of the default button).
  • On Windows, this is a regression in 1.0-rc1.
  • On macOS, the Enter key always clicks the default button, which is the platform behavior.
  • On all platforms, the default button can be always clicked with Ctrl+Enter keys, even if another button is focused.
• CheckBox and RadioButton: Fill component background as soon as background color is different to default background color, even if component is not opaque (which is the default). This paints selection if using the component as cell renderer a Table, Tree or List.

• Custom window decorations: Fixed top window border in dark themes when running in JetBrains Runtime.

1.0-rc1
